The Shunned Omega Becomes a Wealthy Alpha's Fiancée

Because the Jiang family was so deep in debt that they couldn't afford food or school, they sent Jiang Jiang to the He family, where he became the future marriage partner of the young master, He Zhuocheng. He Zhuocheng was fussy, bad-tempered, and hard to please. He looked down on Jiang Jiang as a country bumpkin, hated him, and kept demanding that Jiang Jiang get out of their house and break off the engagement. Jiang Jiang didn't dare talk back. His family was too poor, and he wanted to study and make a lot of money, so he could only put up with the young master and humor him. At first, neither of them could stand the other. He Zhuocheng was disgusted whenever he saw Jiang Jiang, while Jiang Jiang had to bite back his curses as he waited on the young master's every need. Later, He Zhuocheng would panic and go looking for Jiang Jiang whenever he wasn't around. He wanted Jiang Jiang with him at meals, at school, and even when he went to bed at night. Eventually, He Zhuocheng came of age and was able to fulfill the engagement. His mother, worried that her son wouldn't be happy after getting married, suggested that they could call off the marriage. He Zhuocheng panicked. "Who says I don't want to marry him?!" His mother gave him a cool look and played a recording of something He Zhuocheng had once said: "I, He Zhuocheng, swear to heaven that if I ever marry Jiang Jiang, I'll be a dog!" He Zhuocheng touched his nose, blushed, and barked, "Woof." (Basically, it's a story about someone who initially can't stand his spouse, then ends up loving him desperately.) Content warning: The love interest had someone he liked before, but after the protagonist appears, he only has one-sided feelings for him. Theme: Face difficulties bravely and keep moving forward!
